REVERSING GEAR IVIECHANISI FOR ENGINES.

SPECIFICATION forming part of Letters Patent N o. 737,001, dated August25, 1903.

Application led March Z6, 1903. Serial No. 149,742. (No model.)

To all whom, it may concern,.-

Beit known that I, JOHN PETER MosKor, residing at Monrovia, in thecounty of Monroe and State of Illinois, have invented certain new anduseful Improvements in Reversing Gear Mechanism for Engines, of whichthe following is a specification.

My invention seeks to provide a new and improved construction of gearmechanism for reversing the valves of engines embodying a simple,compact, and economical arrangement of parts especially designed to et'-fect the throw or shifting of aneccentric in a positive and convenientmanner; and the same comprehends certain details of construction andpeculiar combination of parts, all of which will hereinafter be fullyeX- plained and specifically pointed out in the appended claim,reference being had to the accompanying drawings, in which- Y Figure 1is a plan view of my invention as applied for use. Fig. 2 is aperspective view of the reversing mechanism. Fig. 3 is a longitudinalsection thereof on the line 3 3 of Fig. l. Fig. i is a cross-section onthe line 4E et of Fig. 1. Fig. 5 is a detail view of the shiftingsleeve, and Fig. 6 is a similar view of the eccentric. Y

In the practical construction the shaft l is mounted in any approvedmanner and carries the usual crank-wheel or disk that joins Amovementwith respect to the shaft.

with the piston-rod, as shown. The shaft l has a feather to engage thelongitudinal groove 3a in thependwise-slidable sleeve 3, which ismounted on the shaft 1 to rotate therewith.

4 designates the eccentric-disk, which has the usual annular groove 4 toaccommodate the strap 5, that joins with the valve-rod o in theusual'manner, and at one side it has a laterally-projecting hub 4b,whose axis is in alinement with the shaft-aperture 4:, which extendsthrough the said hub, as shown. The hub 4J is also provided with anannular groove ZJ, with which engages the ring portion c of a bracket C,disposed transversely of the shaft 1, whose inner ends eX are fixedlyconnected to standards 6, which project up from the base 6, as shown.The bracket C is provided to hold the eccentric from endvise he sleeve2, which is freely movable in the direction of its length through theeccentric, has

tlxedly formed thereon or attached thereto a pair of diametricallyoppositely disposed spiral flanges 2c 2C,that engage with the opposite-spiral grooves 4C 4c in the disk-opening, and at its outer ends thesaid sleeve 2 has annular iianges or rings 9 9, preferably boltedthereto, which serve the double purpose of limiting the throw of thesleeve 2 in reverse directions and for providing side bearings for theeccentric to relieve the bracket 3 from excessive lateral twist straincreated by the rotation of the eccentric thereagainst; Atone end thesleeve 2 has a clutch-groove 2d, adapted to receive a metal ring 10,which has oppositely-projiected studs lOl for engaging with thebifurcated end I1a of a shifting lever Il, which extends to' within'convenient reach of the engineer, is

fulcrurned on a bearing 6C, andprovided with au angle member or handle11b, which may be equipped with the usual spring-pawl devices jparted tothe slide-valve in one direction, and

when the said sleeve is shifted to the position shown in dotted lines inFig. 1 the said slidevalve will have been removed to a reversingposition, it being understood that the said slide-valve can be movedmore or less, according to the throw or movement imparted to the sleeve2 through a proper adjustment of the lever 1l.

Having thusdescribed my invention, what I claim, and desire to secure byLetters Patent, is-

A combination with a shaft, a cylindrical sleeveV rotatable therewithand endwise removable thereon, said sleeve having externally andoppositelydisposed spiral iianges running its entire length and theeccentric mounted on the sleeve and having spiral grooves in its openingto engage the aforesaid spiral anges, and provided with alaterally-projected hub having an annular groove of a flxedly-heldbracket having a ring por- IOO in one end, a band for engaging saidgroove, 1o said band carrying studs, a lever member having a portion forengaging with said studs whereby to shift the sleeve, for the purposestion for encircling and engaging the groove i in the eccentric-hub, anannular rim mounted upon lche shaft and secured to one end of lchesleeve and a second annular rim mounted upon and secured to the sleevenear the other i specified. end thereof; said annular rims serving toenl JOHN PETER MOSKOP. gage the opposite sides of the eccentric-disk lWitnesses:

when the said sleeve is moved in its aiteri nate direction, said sleevehaving a groove l WILLIAM KAISER, JOHN WIERSCH.
